通过vagrant安装centos7
- 下载vagrant box镜像文件
- 将第一步下载virtualbox.box文件添加到vagrant管理的镜像中
(1) 添加镜像并起名叫centos/7：vagrant box add centos/7 D:\VM\vm_box\virtualbox.box
(2) vagrant box list 查看本地的box
-
创建centos7文件夹在此目录下打开cmd，运行vagrant init centos/7。此时会在当前目录下生成Vagrantfile，同时指定使用的镜像为centos/7
-
centos/7镜像有了，根据Vagrantfile文件启动创建虚拟机
来到centos7文件夹，在此目录打开cmd窗口，执行vagrant up【打开virtual box观察，可以发现centos7创建成功】
05 在centos7文件夹打开cmd窗口操作
vagrant halt 关闭系统
vagrant up 正常启动
vagrant reload 使用最新的vagrantfile,重启虚拟机
06 vagrant常用命令
vagrant box remove centos/7 --all 删除centos/7这个镜像的所有版本
vagrant ssh 进入刚才创建的centos7中
vagrant status 查看centos7的状态
vagrant halt 停止/关闭centos7
vagrant destroy 删除centos7实例
Vagrantfile中也可以写脚本命令，使得centos7更加丰富。但是要注意，修改了Vagrantfile，
要想使正常运行的centos7生效，必须使用vagrant reload
使用SSH工具连接centos7
- 在centos文件夹下执行
vagrant ssh-config
关注:
Hostname Port IdentityFile
IP:127.0.0.1
port:2222
用户名:vagrant
密码:vagrant
文件:Identityfile指向的文件private-key`
- 使用root账户登录
vagrant ssh 进入到虚拟机中
sudo -i
vi /etc/ssh/sshd_config 修改PasswordAuthentication yes
执行passwd命令，修改root用户密码，比如abc123
systemctl restart sshd
SSH工具中使用账号root，密码abc123进行登录
Vagrantfile通用写法

# Create a forwarded port mapping which allows access to a specific port

# NOTE: This will enable public access to the opened port

# Share an additional folder to the guest VM. The first argument is

# # Display the VirtualBox GUI when booting the machine
# vb.gui = true
#
# # Customize the amount of memory on the VM:
# vb.memory = "1024"
# end
config.vm.provider "virtualbox" do |vb|
vb.memory = "4000"
vb.name= "centos7"
vb.cpus= 2
end

# View the documentation for the provider you are using for more
# information on available options.
# Enable provisioning with a shell script. Additional provisioners such as
# Puppet, Chef, Ansible, Salt, and Docker are also available. Please see the
# documentation for more information about their specific syntax and use.
